The statement "do not apply where runoff is likely to occur" means what?

The statement "do not apply where runoff is likely to occur" conveys a significant meaning in the context of pest control and chemical applications. This warning emphasizes the potential environmental impact of the chemicals used. When runoff occurs, pesticides may be transported away from the intended target area, which can lead to unintended exposure to non-target species, including beneficial insects, aquatic life, and other organisms in the ecosystem. This highlights the importance of using these chemicals responsibly to prevent ecological harm.

In this context, emphasizing the potential risk of harming non-target species allows applicators to make informed decisions that consider both the effectiveness of the treatment and the safety of the surrounding environment. This understanding is crucial for sustainable pest management practices and aligns with regulatory guidelines that aim to protect the environment while controlling pest populations.
